Billy Kerrigan is a priest who is a friend of Ted Crilly. He was portrayed by series co-creator Arthur Mathews.


He is seen at Ted's birthday party as a guest. Ted previously thought Paul Stone would have gone home by then but was wrong, leading to everyone being depressed while the event was supposed to be a happy one.

In an attempt to break the awkward silence, Billy looks at his watch and attempts to excuse himself while asking if anyone else in the room needs a lift somewhere. The other priests quickly put up their hands and race out of the room but Ted calls Dougal back when he also attempts to leave.
